What is rectifier?
A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction,to direct current (DC),which flows in only one direction.This process is known as rectification. Types of rectifier - There are mainly three types of rectifier. ( 1) Half wave rectifier - A type of rectifier that converts only the half cycle of the alternative current (AC) into direct current (DC) is known as half wave rectifier & only require a single diode to construct. A high AC voltage is applied to the primary side of the step down transformer & it will get a low voltage, which will be applied to the diode. During the positive half cycle of the AC voltage,the diode will be forward biased, for an ideal diode, the forward voltage drop is zero.So the whole input voltage will appear across the load resistance. During the negative half cycle of the AC voltage,the diode will be reverse biased ...
